A ‘Green, Global and Connected’ City

The ‘Five Big Moves’ to manage the City’s growth and to guide future strategic policies and infrastructure:

A revitalised city centre at the heart of global Sydney

An integrated Inner Sydney transport network

A Liveable Green Network (LGN)

Activity hubs as a focus for the City’s village communities and transport

Transformative development and sustainable renewal

Sustainable Sydney

The Liveable Green Network

What it achieves?.....connections to a more liveable city

City Centre Village to village Parks and leisure

The Liveable Green Network

The Liveable Green Network is made up of LGN Priority Network Citywide Pedestrian Priority

Network City Wide Pedestrian Cycle

Priority and Primary Local Pedestrian Network

Primary Local Pedestrian Network

Prepare a Pedestrian Access and Mobility Plan (PAMP) for the LGN Focus on infrastructure audits

and recommendations Audit the four levels of network

priority for: Facility locations and quality Amenity, access and

compliance issues Missing facilities Intersection and crossing

treatments Path condition and widths

The auditing task

The City of Sydney wanted to audit the Liveable Green Network to identify gaps, issues and areas for improvement of the walking experience.

Proposal-stage decisions Calculate kilometres of network Use hand held devices with GIS

software Project commencement

site Trial and revise GIS data

The approach to auditing

Three types of data collection1. Identification and recording of

pedestrian infrastructure.2. Assessment of pedestrian

infrastructure.3. Footpath width

measurements against existing GIS footpath segment layer.

The audit criteria

The location of every non-footpath pedestrian facility was recorded by the site auditors, whether it had any associated issues or not.

Provided Council with an up to date inventory of all pedestrian infrastructure.

1. Identification and recording of pedestrian infrastructure

Every issue associated with pedestrian facilities was recorded by the site auditors. Crossings: dimensions, alignment, condition,

clear zones, signage, missing Path condition: Cracked, uneven (severity:

slight, moderate or severe) Path obstructions: Street furniture,

vegetation, bins, other (degree of impact on the Pedestrian Through Zone)

Sight lines: Conflict at driveways Shared paths: signage, line-marking, pinch

points Shared zones: signage, presence of kerbs,

pavement markings Bus stops: clear space, tactile ground surface

indicators Accessible parking: lack of kerb ramps,

adjacent path width

2. Assessment of pedestrian infrastructure

Footpaths and shared paths Update Council’s footpath segment GIS

layer with the measured width Different widths for paths on the priority

networks Specific measurements were noted as:

below minimum, compliant and preferred Also noted where paths were missing on

the networks

3. Path width measurements

Collecting the data – GIS tool

Collector for ArcGIS IPad application

PAMP data was recorded for the LGN two ways: Placing a point or line to indicate

the presence of a pedestrian facility, record the issue if there were any and to recommend an improvement and;

Updating the footpath segments in the City of Sydney footpath layer to include a value for the measured width of each footpath segment.

Collecting the data

The site audits were undertaken between December 2014 – February 2015.

A team of up to five people a day audited the LGN, focusing on one area of the City at a time.

Each team member had a measuring tape and used the tablet’s in built camera.

Each auditor required two tablets each day due to battery drainage.

Collecting the data

Eight weeks of audits

Works were prioritised based on their location within high, medium or low priority areas throughout the CBD

New works were prioritised higher than upgrade works

The complete data collection was presented in a geodatabase for the City of Sydney. The geodatabase includes: Unique point or line ID. Location of pedestrian facilities. Type and severity of pedestrian facility issues (if any). Photo. Recommended improvement (if required). Cost estimate. Priority. Updated widths for the City of Sydney footpath segment layer
